MP4tiedostojen

MP4tiedostojen, often referred to as MP4 files, are a digital multimedia container format most commonly used to store video and audio, but they can also store other data such as subtitles and still images. The MP4 format is standardized by the Moving Picture Experts Group (MPEG) and is an evolution of the MPEG-1 and MPEG-2 formats. The official file extension for MP4 files is .mp4, but other extensions like .m4v and .m4a are also used for specific types of MP4 content.

The flexibility of the MP4 container allows it to support a wide range of audio and video codecs, making it compatible with a vast array of devices and software. Common video codecs used within MP4 files include H.264 (AVC) and H.265 (HEVC), known for their efficient compression. For audio, AAC (Advanced Audio Coding) is frequently used. MP4 files are widely used for online video streaming, digital television broadcasting, and storing video content on portable devices. Their widespread adoption is due to their ability to offer good quality video and audio while maintaining relatively small file sizes. Playing MP4 files typically requires a compatible media player or software that supports the specific codecs used within the container.
